A LOW COST/HIGH QUALITY resistance or fluid level control with Built-in holding circuit. Two SPST relays - the second relay to operate remote signal devices or a secondary pump. Screw terminals for easy field installation.
Ideal product for stocking distributors or manufacturers who need OFF-THE-SHELF versatility without large stock investments.
PUMP DOWN-output remains ON until the absence of liquid (HIGH RESISTANCE) on probe circuit.
PUMP UP-output remains ON until the presence of liquid (LOW RESISTANCE) on probe circuit.
Detection of level conditions in Tanks, Sumps, Reservoirs, Wells or Pools, Vending Machines, Water Softeners, Dishwashers, Coffee Makers, Ice Machines. Food, Dairy, Brewing and Chemical Processing. Metal to Metal Contact Detection in Conveyor and Robotic Applications. Leak Detection in Ducts, Sub-Floors, etc.
Probes, Float, Flow, Pressure Switches, Thermostats, Push-button Actuators, Temperature, Pressure, Humidity.
